Summary:An optical switch module including a light generation circuit, a light receiving circuit, and a control unit is provided. The light generation circuit includes a light generation unit and a control end, and generates light according to a control signal from the control end. The light receiving circuit includes a light receiving unit and a signal reading end, and is configured to receive light to generate a detection signal at the signal reading end. The control unit is configured to generate the control signal and receive the detection signal. The control unit further selectively configures the signal reading end in an input mode or an output mode. Before the control unit configures the signal reading end in the input mode to read the detection signal, the control unit configures the signal reading end in the output mode to pull up a potential of the light receiving unit.
